QNT-2 Thickness gauge is used for measuring on line. Since the high-sensitivity ionization chamber and high quality integrated circuits are adopted, high reliability, stability and the convenience of operation and maintenance is to get. It may be used with optional pneumatic C-frame.

Specification
Measuring range: 0~4mm (for Fe)
Nonlinearity: Less than ±0.3% or ±3µm
Sensitivity: 0.01mm or 0.001mm (selected by switch)
Noise (±µm): <1µm for 0.5mm. <2µm for 1mm
Drift: Less than ±0.01mm/24h (when temperature change should be within ±5?)
Time constant: 0.5sec (63% response for 5% change in thickness)
Sampling time: 3time/sec

QNT-4 Thickness gauge is used for measuring on line and automatic controlling the thickness on line. It displays the absolute thickness (digit) and the deviation of thickness (digit and analog). It has the output of absolute thickness (binary or 8.4.2.1 code), the output deviation thickness (8.4.2.1 code) and the analog output of deviation thickness for record and communication with industrial computer. Since the high-sensitivity ionization chamber and microprocessor are adopted, its “0 Point” can be adjusted automatically, high-accuracy measurement is possible to get. It may be with optional frame.
